APPARATUS TOR FPRINTING CARPET YARNS.

1 aZZ whom, it may concern:

Be it known that 1, JOHN G. DOAK, a citizen-of the-United States, residing at Amsterdam, in the county of Montgomery and State of New York, have invented new and useful Improvements in Apparatus for Printing Carpet Yarns, of which the following is a specification.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

This invention relates to apparatus for printing stripes of different colors transversely of strands of carpet yarn on a drum preparatory to incorporating the yarn in a carpet fabric.

The principal object of the invention is to recover and save surplus color applied to the yarn in the printing operation.

Other objects will appear in connection with the following description.

Fig. 1 of the drawings is a View in side elevation partly broken away showing the color-carriage, a portion of the yarn drum and the color-return trough embodying my invention.

Fig. 2 is a central vertical longitudinal section taken through the scraper which removes the surplus color from the yarn and broken-away portion of the color-box.

Fig. 3 is a top plan view of a brokenaway part of the color-carriage showing the scraper and color-return trough.

Fig. 4 is a cross section taken on the broken line H in Fig. 2. a

Fig. 5 is a cross section taken on the broken line 5-5 in Fig. 2.

Referring to the drawings wherein the invention is shown in preferred form, 1 is the drum upon which the yarn, 2, is wound. 3 is the color-carriage movable along tr ackrails, 4, longitudinally of, and directly be neath, the drum, 1.

Mounted upon the color-carriage, 3, is a color-wheel, 5, which distributes a stripe of color transversely to the yarn wound on the drum, 1.

The color-wheel, 5, is rotatively mounted upon the carriage, 3, with its lower portion immersed in the liquid color contained within the color-box, 6,, also mounted upon the carriage, 3.

A scraper, 7, is mounted upon the car riage, 3, somewhat beyond one end of the 1924. Seria1 .No. 71 1,"/.32.

color-box, 6, and approximately in line, with the color-wheel, 5.

The carriage, 3, is moved in. opposite clirections in the usual 'manner'longitudinally of the drum, 1. The carriage-operating means being well understood in the art, is not shown in the drawings. 7

As the carriage, 8, is moved in one direction, a. stripe of color is applied to or printed upon the yarn, 2, on the drum, '1, and upon the return movement of the carriage, the scraper, 7, scrapes'oli' the surplus color from the yarn.

In carrying out my invention, I mount upon the color-carriage, 3, a return-trough, 8, extending from below the scraper, 7, to the color-box, 6.

As the scraper, 7, operates upon'the yarn to remove the surplus color therefrom, the removed color flows down into the returntrough, 8, and therefrom into the colorboX, 6.

'In adapting the apparatus for printing stripes of different colors upon the yarn, it is necessary to from time to time remove the color-box, 6..

I have shown the return-trough, 8, pro vided with a vertically oscillatory spout, 8*, overhanging the neighboring end of the color-box, 6.

hen it is desiredto remove the color-box,

6, from the carriage, 3, the spout, 8 can be swung upwardly to the position indicated by dotted lines in Fig. 1, out of the path of removal of the color-box. 7

By the use of my invention the surplus color removed from the yarn is immediately returned to the color-box, thus preventing waste of the color and maintaining uniformity in the shade of the color.

The return-trough, 8, including its spout, 8 may be made of sheet metal or other suitable material.

I do not wish to be limited to the con structions shown and above described, as, for certain purposes of the invention, various changes may be made in the form and arrangement of various parts of the device without departing from the spirit of the invention.

\Vhat I claim as new and desire to secure.

yarn; and a return-trough for surplus color extending from below said scraper to the color-box.

2. In an apparatus for printing carpet yarn, and in combination, a yarn-drum; a colo-r-distributing-wheel; a color-box; a scraper for removing surplus color from the yarn; and a return-trough for surplus color extending from below said scraper and having a vertically oscillatory spout overhanging the color-box.

3. In an apparatus for printing carpet yarn, and in combination, a yarn-drum; a color-carriage; a color-box; a color-distributing-wheel; a scraper for removing surplus color from the yarn; and a returntrough extending from below the scraper to the color-box, said color-box, distributingwheel, scraper and return-trough being mounted on said carriage.

In testimony whereof I have hereunto set my hand this 29 day of April, 1924.
